Referring to FIGS. 1 to 5, a refrigerator 10 according to an embodiment of the present disclosure may include a cabinet 11 in which a storage space is defined, a door 12 which is rotatably mounted on a front surface of the cabinet 11 to open and close the storage space, and a beer brewing device installed on the rear surface of the door 12. The storage space may include at least one of a refrigerating chamber and a freezing chamber. The door 12 may be a refrigerating chamber door for opening and closing the refrigerating chamber or a freezing chamber door for opening and closing the freezing chamber.

In detail, the beer brewing device installed on the rear surface of the door 12 may apply the configurations of the beer brewing device described in the prior art. However, the beer brewing device according to the prior art is provided with a separate water tank for storing water necessary for beer brewing, but the beer brewing device installed in the refrigerator according to the embodiment of the present disclosure does not require a water tank.

Specifically, the door 12 is provided with a dispenser 14 for ejecting purified water or cold water, and the water supply flow path 101 connected to the dispenser 14 is directly connected to a faucet in the house.

One end of the water supply flow path 101 is connected to a faucet in a house and may extend inside the cabinet 11 or along the rear surface of the cabinet 11. In addition, the water supply flow path 101 may pass through an upper surface of the cabinet 11 to be guided into the storage space, and a filter assembly 104 may be connected to one side of the water supply flow path 101.

A branch valve V may be mounted at any point of the water supply flow path extending from an outlet of the filter assembly 104, and a plurality of branch flow paths may be connected to the branch valve.

The plurality of branch flow paths may include a drinking water flow path 103 through which water drinkable by a user flows, and a beer brewing flow path 102 through which water supplied to the beer brewing device and used for beer brewing flows.

The drinking water flow path may include at least one of a purified water flow path through which purified water passing through the filter assembly flows at room temperature, a cold water flow path through which cold water cooled to a temperature corresponding to a refrigerating chamber temperature flows, and a hot water flow path through which hot water flows.

A cold water tank may be provided on the cold water flow path, and a heating device may be provided in the hot water flow path. The cold water tank may be disposed inside the refrigerating chamber or a refrigerating chamber door that opens and closes the refrigerating chamber, so that the temperature of the cold water tank may be maintained at the refrigerating chamber temperature. The cold water tank may be formed by winding the water supply flow path multiple times or may be provided in the form of a separate cold water storage tank.

In addition, the heating device may include a hot water tank and a heater for heating the hot water tank.

An end portion of each of the purified water flow path, the cold water flow path, and the hot water flow path may be connected to one ejection nozzle, and the ejection nozzle may be connected to the drinking water ejection cock 144 provided in the dispenser 14.

In addition, the water supply flow path 101 may pass through the hinge of the door 12 and extend from the cabinet 11 to the door 12. The branching flow path may be branched at any point of the water supply flow path 101 extending into the inside of the door 12 through the hinge of the door.

As described above, since purified water passing through the filter assembly extends to the beer brewing device along the beer brewing flow path 102, there is no need to separately install a water storage tank for storing water used in beer brewing in the door 12 or the cabinet 11.

Meanwhile, the door 12 may include an outdoor 121 that is in close contact with the front surface of the cabinet 11 and forms the outer shape of the refrigerator 10, a door liner 122 which extends from the rear surface of the outdoor 121 to be accommodated in the inside of the storage space, a home brew housing 16 provided on the rear surface of the outdoor 121, and a gasket 123 wrapped around the rear surface of the outdoor 121 corresponding to the edge of the door liner 122.

The home brew housing 16 extends from the rear surface of the outdoor 121 and has a space formed therein so that the door liner 122 and the home brew housing 16 may be formed in a box shape without division and may be formed in a box shape detachably coupled to the rear end of the door liner 122.

The dispenser 14 may be provided on the front surface of the outdoor 121, and an ejection member 13 for ejecting beer may be installed on the upper side of the dispenser 14.

A beer ejection pipe (not illustrated) extending from the upper surface of the fermentation tank 25 constituting a beer brewing device to be described later extends along the inside of the lever body 131 and is connected to the ejection cock 133. Accordingly, beer completed in the fermentation tank 25 may flow along the beer ejection pipe and be discharged to the outside through the ejection cock 133. In addition, the flow path of the beer ejection pipe is selectively opened and closed by the tilting operation of the ejection lever 132.

The dispenser 14 may include a dispenser housing 141 recessed backward at a predetermined depth, a residual water tray 142 installed on the bottom of the dispenser housing 141, and a drinking water ejection button 143 installed on the rear surface of the dispenser housing 141, and a drinking water ejection cock 144 protruding from the upper surface of the dispenser housing 141.

The residual water tray 142 is provided so as to be capable of ejecting forward and can be used as a stand for a container for receiving beer. In addition, even when the volume of the container for receiving drinking water is large, the remaining water tray 142 can be ejected. A plurality of slits are formed on the upper surface of the residual water tray 142, and a predetermined storage space is formed therein so that beer or drinking water falling from the ejection cocks 133 and 144 can be collected.

In addition, a display 15 is installed at a point on the front surface of the outdoor 121 spaced upward from the dispensing member 13, so that various information related to the beer brewing and the beer ejection can be displayed to the user.

For example, the beer brewing completion time or the current beer brewing progress can be checked through text, image, or video information output through the display 15.

Meanwhile, the inside of the home brew housing 16 may be divided into a lower machine room 161 and an upper input chamber 162.

In detail, the home brew housing 16 may include a side plate 169 which is wrapped along the rear surface of the outdoor 121 or the end portion of the door liner 122, a front plate 168 connecting to the front end portion of the side plate 169, a base plate 167 forming the bottom of the side plate 169 and the front plate 168, and an upper plate 160 dividing the machine room 161 and the input chamber 162. The upper plate may be defined as a division plate dividing the machine room 161 and the input chamber 162.

In a state where the door 12 is open, an opening 163 is formed in the upper portion of the home brew housing 16 corresponding to the front surface of the input chamber 162, and the opening 163 may be selectively opened and closed by the input chamber cover 17. In addition, the input chamber cover 17 may also be understood as a component of the home brew housing 16.

The input chamber cover 17 is rotatably mounted on one side edge of the opening 163 and can selectively open and close the input chamber 162.

One or a plurality of accommodation boxes 18 may be provided on the rear surface of the input chamber cover 17 (the surface facing the input chamber), and raw materials for beer brewing or other storage items may be accommodated in the accommodation box 18.

In addition, since the input chamber cover 17 is made of a transparent or translucent plastic material, it is possible to check the inside of the input chamber 162 even when the input chamber cover 17 is closed.

A pack accommodation box 19 may be installed above the input chamber 162, and a main material storage pack 20 may be stored in the pack accommodation box 19. As an example, the main material storage pack 20 may have a cylindrical shape having a predetermined diameter and length.

The main material storage pack 20 may contain a main material essential for beer brewing, and the main material may include malt in a relatively large amount among materials necessary for beer brewing.

The pack accommodation box 19 may be provided to be slidably drawn out in the front and rear direction. For example, sliding guides may extend a predetermined length in the front and rear direction on both sides of the pack accommodation box 19, and guide grooves accommodating the sliding guides may be formed on both sides of the input chamber 162. Alternatively, the sliding guides may be formed on both sides of the input chamber 162 and guide grooves may be formed on both sides of the pack accommodation box 19.

In addition, a pack insertion port (or pack insertion port) 164 into which the main material storage pack 20 is inserted may be formed in the upper plate 160, and a capsule mounting portion 165 may be formed on the side of the pack insertion port 164.

A plurality of capsule mounting grooves 166 may be disposed in a row in the capsule mounting portion 165. Each of the capsules 24 containing raw materials for beer brewing may be mounted in the capsule mounting grooves 166.

Auxiliary materials for beer brewing may be stored in the capsule 24, and the auxiliary materials may include other materials other than malt stored in the main material storage pack 20. For example, the auxiliary materials may include yeast, hops, and flavor additives.

In addition, a pack insertion port cover 21 is rotatably mounted on an edge of the pack insertion port 164 to open and close the pack insertion port 164. In addition, a capsule mounting portion cover 22 is rotatably connected to an edge of the capsule mounting portion 165 to cover the capsule mounting portion 165.

The capsule mounting portion 165 may be formed stepwise with a depth corresponding to the thickness of the capsule mounting portion cover 22. Therefore, when the capsule mounting portion cover 22 is closed, the upper surface of the capsule mounting portion cover 22 and the upper surface of the upper plate 160 may form the same plane.

A plurality of lockers 23 covering the upper surface of the capsule 24 are provided on the bottom surface of the capsule mounting portion cover 22, so that when the capsule mounting portion cover 22 is placed on the capsule mounting portion 165, the lockers 23 are in close contact with the upper surfaces of the capsules 24, respectively.

In addition, as illustrated in FIG. 5, when the main material storage pack 20 is inserted into the pack insertion port 164 and then the pack insertion port cover 21 is closed, the upper surface of the pack insertion port cover 21 may form the same surface as the upper surface of the upper plate 160.

In addition, the pack insertion port cover 21 may include a cover body 211 and a handle 212 formed inside an upper surface of the cover body 211. In addition, a handle 221 may be formed on an upper surface of the capsule mounting portion cover 22.

Meanwhile, inside the machine room 161, as illustrated in FIG. 5, various mechanical devices and electrical devices for beer brewing are accommodated. In other words, configurations for beer brewing disclosed in the above prior art can be disposed.

Among the configurations necessary for beer brewing, only the configurations illustrated in the drawings will be described.

The configuration for beer brewing accommodated in the machine room 161 may include the fermentation tank 25 in which the main material storage pack 20 is accommodated, and a cooling module for maintaining the inside of the fermentation tank 25 at an optimal temperature for beer brewing, and valves installed in a pipe connected to the fermentation tank 25.

The pipe connected to the fermentation tank 25 may include a water supply pipe defining the beer brewing flow path 102.

The beer brewing flow path 102 passes through the capsule 24 and is connected to the inside of the main material storage pack 20, so that the auxiliary materials stored in the capsule 24 are supplied to the main material storage pack 20 together with water.

In addition, the pipe connected to the fermentation tank 25 may further include a beer supply pipe connecting the fermentation tank 25 and the ejection cock 133.

In addition, the valves installed in the pipes may include a capsule valve V1 installed in the connection pipe connecting the capsule 24 and the main material storage pack 20, and a beer ejection valve V2 installed in the beer supply pipe.

When the supply of water for beer brewing starts, the capsule valve V1 is opened so that the auxiliary material and water are supplied to the main material storage pack 20.

In addition, when the beer brewing is completed and the ejection lever 132 is operated, the beer ejection valve V2 is opened so that beer is ejected through the ejection cock 133.

In addition, although not illustrated, it should be noted that opening/closing valves may be installed in each of a plurality of pipes including a gas discharge pipe for discharging gas inside the fermentation tank 25.

In addition, the cooling device may include a compressor 30 for compressing refrigerant, a condenser 31 connected to the outlet side of the compressor, an expansion valve connected to the outlet side of the condenser 31, and an evaporator 32 connected to an outlet side of the expansion valve.

The cooling device is a separate cooling device that is distinguished from a cooling device installed in a cabinet to cool a refrigerating chamber or a freezing chamber of a refrigerator.

The evaporator 32 is wrapped around the outer circumferential surface of the fermentation tank 25 so that the inside of the fermentation tank 25 is maintained at a temperature suitable for fermentation. A heater 33 is wrapped around the outer circumferential surface of the fermentation tank 25 so that the inside of the fermentation tank 25 may be heated to a set temperature.

As illustrated in FIG. 5, the main material storage pack 20 is inserted into the fermentation tank 25 through the pack insertion port 164, and then the pack input port cover 21 is closed, and the auxiliary material storage capsule 24 mounts in the capsule mounting groove 166 and then when the capsule mounting portion cover 22 is closed, preparation for beer brewing is completed.

In this state, when a beer brewing command is input through the control panel provided on the door 12 of the refrigerator 10, water is supplied to the fermentation tank 25 through the beer brewing flow path. Then, the compressor and the heater 33 of the cooling device are operated at the set time to perform the beer brewing process.

According to the configuration as described above, the user can eject beer by manipulating the ejection lever 132 provided on the front surface of the refrigerator door 12.

In addition, since the user can easily replace the main material storage pack 20 and the auxiliary material storage capsule 24, there is an advantage in that the user can make and drink beer without any difficulty.

Above all, since a separate installation space for installing the beer brewing device is not required, there is an advantage in that the indoor space can be efficiently utilized.

FIG. 6 is a front perspective view illustrating a refrigerator door according to another embodiment of the present disclosure equipped with a beer brewing device, FIG. 7 is an enlarged perspective view illustrating a dispensing member for ejecting beer, and FIG. 8 is an enlarged perspective view illustrating a dispenser provided in a door.

Referring to FIGS. 6 to 8, this embodiment is characterized in that the structure of the ejection cock 133 is different from the structure of the ejection cock 133 described in the previous embodiment. In detail, the ejection cock 133 according to another embodiment of the present disclosure may include a front cock 133a located at the front and a rear cock 133b located at the rear of the front cock 133a.

A beer ejection pipe (not illustrated) extending from the upper surface of the fermentation tank 190 (see FIG. 13) constituting a beer brewing device to be described later extends along the inside of the lever body 131 to be connected to the ejection cock 133. Accordingly, the beer completed in the fermentation tank 1900 may flow along the beer ejection pipe and be discharged to the outside through the ejection cock 133. In addition, the flow path of the beer ejection pipe is selectively opened and closed by the tilting operation of the ejection lever 132.

In addition, when there are a plurality of fermentation tanks 190, among the plurality of fermentation tanks 190, the fermentation tank 190 currently supplying beer or in a state where beer can be supplied may be displayed on the display 15.

The user can set the order in which beer is to be consumed from which fermentation tank 190 among the plurality of fermentation tanks 190 through the main control panel C of the refrigerator 10 equipped with the plurality of fermentation tanks 190.

Meanwhile, in this embodiment, unlike the structure of the previous embodiment in which a separate cooling device is installed inside the home brew housing 16, it is characterized in that cold air is supplied from an evaporation chamber (not illustrated) supplying cold air to the storage space of the cabinet 11 into the home brew housing 160. Therefore, the cooling device for maintaining the inside of the fermentation tank 190 at a temperature suitable for beer brewing may be understood as a cooling device for cooling a storage space of a refrigerator. To this end, a cold air supply port 16a and a cold air discharge port 16b may be formed on the side surface of the home brew housing 160. The cold air supply port 16a may be formed above the cold air discharge port 16b.

In addition, a cold air supply duct and a cold air recovery duct may extend along the inside of the sidewall of the cabinet 11, and when the door 12 is closed, the outlet end of the cold air supply duct may be in contact with the cold air supply port 16a. and the inlet end of the cold air recovery duct may be in contact with the cold air discharge port 16b.

In addition, an inlet end of the cold air supply duct may communicate with an evaporation chamber in which an evaporator is installed, and an outlet end of the cold air recovery duct may communicate with the evaporation chamber or a storage chamber formed inside the cabinet. For example, the storage space communicating with the outlet end of the cold air recovery duct may be a freezing chamber.

According to this structure, the inside of the home brew housing 16 can be maintained at a refrigerating temperature by the cold air flowing into the home brew housing 16 through the cold air supply port 16a. In other words, the fermentation tank 19 housed in the home brew housing 16 can always be maintained at a refrigerating temperature. As a result, since the beer stored in the fermentation tank 190 can be maintained in the range of 3° C. to 5° C., the user has the advantage of always drinking low-temperature beer.

In addition, it should be noted that the cold air supply structure is also applicable to the refrigerator according to the embodiment illustrated in FIGS. 1 to 5.

FIG. 9 is a rear perspective view illustrating a refrigerator door equipped with a beer brewing device according to another embodiment of the present disclosure, and FIG. 10 is a rear perspective view of a refrigerator door illustrating a state where a main material storage pack constituting a beer brewing device according to another embodiment of the present disclosure is drawn in and out.

A back pressure 1810b is mounted on the rear surface of each of the first case cover 1810 and the second case cover 1820 and thus the first case cover 1810 and the second case cover 1820 can be pressurized and be in close contact with the upper surface of the main material storage pack 20.

In addition, the fermentation tank case 170 may be rotated or tilted by a predetermined angle from the lower housing 1610 so that the case cover 180 may be exposed to the outside.

In a state where the fermentation tank case 170 is tilted, the case cover 180 is rotated upward to open an insertion portion for inserting the main material storage pack. In addition, after inserting the main material storage pack 20 into the insertion portion, the case cover 180 is closed, and the fermentation tank case 170 is tilted in reverse so that the front surface of the fermentation tank case 170 forms the same surface of the upper housing 1620.

Here, the front surface of the fermentation tank case 17 and the front surface of the upper housing 162 may be defined as the surfaces facing the rear surface of the storage space of the refrigerator 10 when the door 12 is closed or the opposite side of the front side of the outdoor 121.

FIG. 11 is a rear perspective view of the door illustrating a state where an auxiliary material storage cassette is drawn in and out, and FIG. 12 is a bottom perspective view illustrating an auxiliary material storage cassette.

The first cassette 61 and the second cassette 62 may be spaced apart from each other in the vertical direction. Of course, cassette insertion ports 1640 for inserting the first cassette 61 and the second cassette 62 may be formed in the division wall 1630.

More specifically, the first cassette 61 may include a first cassette body 611 in which a first capsule seating portion 612 is recessed, and a first capsule 613 inserted into the first capsule seating portion 612. A plurality of first capsule seating portions 612 may be disposed in a row on the upper surface of the first cassette body 611.

Like the first cassette 61, the second cassette 62 may include a second cassette body 621 and a second capsule 623, and a plurality of second capsule seating portions 622 may be recessed on the upper surface of the second cassette body 621.

When the first cassette 61 and the second cassette 62 are completely inserted into the cassette insertion port 164, the front surfaces of the first cassette 61 and the second cassette 62 may be designed to form the same surface as the front surface of the division wall 163.

In addition, a push-pull switch may be mounted on rear surfaces of the first cassette 61 and the second cassette 62, and a switch groove into which the push-pull switch is inserted may be formed on a surface corresponding to the rear surface of the division wall 1630.

According to this structure, when the user presses and releases the front surfaces of the first cassette 61 and the second cassette 62, the first cassette 61 and the second cassette 62 jump forward a certain distance. In addition, the user may hold the first cassette 61 and the second cassette 62 by hand and pull them so that the capsule seating portions 612 and 622 are exposed to the outside. In this state, the user can replace the capsules 613 and 623.

FIG. 13 is a rear perspective view of a door illustrating an internal configuration of a home brew housing equipped with a beer brewing device, and FIG. 14 is a longitudinal cross-sectional view of the door taken along line 14-14 of FIG. 13.

Referring to FIGS. 13 and 14, the inner space of the upper housing 1620 may be defined as a machine room 1620a, and the inner space of the lower housing 1610 may be defined as a brewing chamber.

In detail, the brewing chamber may include a first brewing chamber 1610a in which the first fermentation tank case 1710 is accommodated and a second brewing chamber in which the second fermentation tank case 1720 is accommodated.

The brewing chamber and the machine room 1620a may be divided by a mullion 1650. In addition, a heat insulating material is injected into the mullion 1650 to prevent transfer of heat inside the machine room 1620a to the inside of the brewing chamber by heat conduction.

The fermentation tank 190 is accommodated in the fermentation tank case 170, and the fermentation tank 190 may includes the first fermentation tank 1910 accommodated in the first fermentation tank case 1710 and a second fermentation tank 1920 accommodated in the second fermentation tank case 1720.

As another embodiment, a cooling device 40 for cooling the fermentation tank 190 may be disposed inside the machine room 1620a.

Unlike the embodiment in which the cooling device is accommodated in the same space as the home brew housing and the embodiment in which cold air is supplied from the evaporation chamber of the refrigerator without a separate cooling device, an embodiment in which the cooling device except for the evaporator is disposed in the machine room 1620a is also possible.

In detail, the cooling device 40 may include a compressor 401 that compresses the refrigerant, a condenser 402 that condenses the refrigerant, an expansion valve that expands the refrigerant, and an evaporator that evaporates the refrigerant.

The compressor 401, the condenser 402, the expansion valve, and the evaporator may be connected by a refrigerant pipe to form a closed circuit.

The refrigerant pipe defined as the evaporator is wound around the outer circumferential surface of the fermentation tank 190 in a spiral shape, so that the inside of the fermentation tank 190 is maintained at a temperature suitable for beer brewing.

In addition, a plurality of valves 403 are accommodated in the machine room 162a, and the plurality of valves 403 may be mounted on a water supply pipe defining the beer brewing flow path 102, a connection pipe connecting the main material storage pack 20 and the cassette 60, and a beer supply pipe 106 connecting the fermentation tank 190 and the ejection cock 133, respectively.

The beer supply pipe 106 may include a front pipe 106a connected to the front cock 133a and a rear pipe 106b connected to the rear cock 133b.

In addition, since the compressor 401 and the condenser 402 are components that emit heat to the outside, unlike the expansion valve or the evaporator, the compressor 401 and the condenser 402 are wrapped by a heat insulating member, and thus heat emitted from these may be discharged to the storage space of the refrigerator 10 to prevent an increase in load in the storage space.

Meanwhile, both sides of the division wall 1630 and one side surfaces of the first fermentation tank 1910 and the second fermentation tank 1920 facing both sides of the division wall 1630 may be provided a guide means for guiding tilting of the fermentation tank 190 in the forward and backward direction, respectively.

As illustrated, the draw-out guide groove 1630a may be formed in an arc shape having a predetermined curvature, and the guide protrusion 1730 is inserted into the draw-out guide groove 1630a.

In addition, the fermentation tank 190 may be tilted until the guide protrusion 1730 is caught on one end portion of the draw-out guide groove 1630a. Conversely, when the fermentation tank 190 is completely inserted into the lower housing 1610, the guide protrusion 1730 is caught on the other end portion of the draw-out guide groove 1630a.

FIG. 15 is a longitudinal cross-sectional view of the refrigerator door taken along line 15-15 of FIG. 13, and FIG. 16 is a view schematically illustrating the configuration of the latch assembly provided in the fermentation tank case.

In a state where the fermentation tank case 170 is completely inserted into the first brewing chamber 1610a, the front end of the catching portion 541 is caught in the latch hole 161b, so that the fermentation tank case 170 is not tilted by itself.

In order to tilt the fermentation tank case 170, the user pulls the handle portion 511 by hand. Then, the handle 51 rotates in one direction (in the direction of the arrow in the drawing) around the rotation shaft 512, and the pressing portion 513 presses the end portion of the first link 521.

As the first link 521 rotates, the end portion of the second link 523 rises, and as a result, the vertical link 53 rises.

As the vertical link 53 rises, the catching portion 541 is lifted so that the front end of the catching portion 541 is separated from the latch hole 161b.

At this time, a push spring S is mounted on the wall surface of the first brewing chamber 161a so that a force pushing the fermentation tank case 1700 can act. Then, in a state where the front end of the catching portion 541 is lifted, the front end of the catching portion 541 is separated from the latch hole 161b by the elastic force of the push spring S. In addition, the fermentation tank case 170 is tilted by a predetermined angle by the elastic force of the push spring S.

In this state, the user may tilt the fermentation tank case 170 by gripping and pulling the upper end portion of the fermentation tank case 170 or rotating the hand holding the handle portion 511.

Meanwhile, a communication hole 163a is formed in the division wall 163 so that a first brewing chamber 1610a in which the first fermentation tank case 1710 is accommodated and a second fermentation tank case 1720 in which the second fermentation tank case 1720 is accommodated may communicate with each other.

Then, the cold air introduced through the cold air supply port 16a is supplied to the first brewing chamber 1610a and the second brewing chamber, so that the first fermentation tank case 1710 and the second fermentation tank case 1720 may be maintained in a refrigerated state.
